PVC View

The PVC view displays the PV/PVC status and usage.

The following PVC types support usage monitoring:

EVS PVCs (The value of volumeMode must be Filesystem.)
Local PVCs (The Everest version installed in the cluster must be 2.4.41 or later.)
SFS Turbo PVCs (Subdirectories generated dynamically by SFS Turbo also support usage monitoring. However, the PVC usage and capacity collected from the subdirectories are the same as those of the SFS Turbo instance).
PVCs mounted to common containers (The usages and inodes usages can be collected for such PVCs, but not for the PVCs mounted to secure containers.)

You can view PVC metrics in the following table.

**Table 1** PVC metrics
Metric	Unit	Description
PV Status	N/A	PV status, which can be Available, Bound, Failed, Pending, or Released.
PVC Status	N/A	PVC status, which can be Bound, Lost, or Pending.
Used PVC	GiB	Used and available PVC space.
PVC Usage	%	Percentage of a PVC that is used.
Used Inodes in PVC	N/A	Used and available space of inodes in a PVC.
Inodes Usage in PVC	%	Percentage of inodes that are used in a PVC.

The following is the metric list of the PVC view.
